randconfig does randomize choices.


masahiro@pug:~/ref/linux$ make -s randconfig ; grep OPTIMIZE_FOR .config
KCONFIG_SEED=0x75F1F6C8
CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE=y
# CONFIG_CC_OPTIMIZE_FOR_SIZE is not set
masahiro@pug:~/ref/linux$ make -s randconfig ; grep OPTIMIZE_FOR .config
KCONFIG_SEED=0x8FDFC7FC
# CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE is not set
CONFIG_CC_OPTIMIZE_FOR_SIZE=y


all{yes,mod}config always takes the default in the choice.
So, you cannot enable CONFIG_CC_OPTIMIZE_FOR_SIZE by all{yes,mod}config.

OK, then.


Thanks.
